Got Questions About U.S. Steel’s Proposed Hot Strip Mill? Get Answers Thursday

If you’ve been following environmental news around the Mon Valley, you know big shifts are on the horizon.
The Allegheny County Health Department (ACHD) is hosting an upcoming public information session and Q&A focused on the air quality permits for U.S. Steel's proposed Hot Strip Mill project at the Edgar Thomson Plant in Braddock at 5 p.m. Thursday.
This session is a crucial opportunity to get the facts straight from regulators, ask hard questions, and prepare your voice for the public comment process. We hope you can join us there.
What's the Deal with the Hot Strip Mill?
U.S. Steel wants to build a brand-new hot strip mill directly at the Edgar Thomson facility. On paper, moving operations away from older equipment like the Irvin Plant sounds like an operational shift, but local residents and air quality advocates know the full picture requires a much closer look:
Long-Term Lock-In: A major infrastructure investment like this can lock in dirty industrial processes and high carbon footprints for decades to come.
PM2.5 Concerns: Fine particulate matter (or PM2.5) remains a persistent public health challenge in Allegheny County, particularly near industrial corridors.
It Shifts the Pollution Burden: Recent modeling by our friends at Carnegie Mellon University’s CREATE Lab demonstrates that shutting down Irvin Plant while adding proposed operations in Braddock would significantly broaden the overall emission footprint across surrounding communities.
Why You Should Attend
We get it, friends: Permit processes can feel overwhelming, but showing up as a community makes a real difference. Attending this info session will help you:
Learn directly from ACHD staff about what is being proposed and how air emissions will be regulated.
Ask questions about local monitoring, enforcement mechanisms, and public health safeguards during the live Q&A.
Pick up actionable key points to prepare your official public comments when draft air permits are up for review.
What You Need to Know If You Wanna Go
The meeting will be held from 5 p.m. to 7 p.m. Thursday, Oct. 15 at Carnegie One Braddock library.
Quick note: Food and childcare will be provided thanks to our partners at PennFuture, North Braddock Residents for Our Future, and Breathe Project.
